Thermoelectric power generation based charging apparatus and manufactured charging wristband

Abstract

The invention provides a thermoelectric power generation based charging apparatus. The charging apparatus comprises a thermoelectric power generation apparatus, a buffer switching circuit, a charging management chip, and a paper battery, wherein the thermoelectric power generation apparatus comprises two HOT panels; a COLD panel is arranged between the two HOT panels; a PN integrated chip is arranged between each HOT panel and the COLD panel separately, so that each HOT panel, the corresponding PN integrated chip and the COLD panel form a set of sub generator; then the sub generators are in cascade connection to form the thermoelectric power generation apparatus; the buffer switching circuit is connected to the outside of the thermoelectric power generation apparatus; and the paper battery is used for storing the electric energy generated by the thermoelectric power generation apparatus. A charging wristband based on the thermoelectric power generation is manufactured as well. Conversion from movement thermal energy to electric energy is realized due to the introduction of the semiconductor thermoelectric power generation, and a passive charging apparatus is provided; then the passive charging apparatus is designed into the charging wristband form suitable for wearing; therefore, passive charging of a mobile phone and the like is solved; and an emergency and meticulous passive charging solution for electronic equipment used in outdoors is provided.

Description

technical field [0001] The invention relates to the field of power sources, in particular to a charging device based on thermoelectric power generation and a charging bracelet made thereof. Background technique [0002] With the rapid development of information technology and hardware technology, smart phones have gradually replaced computers as entertainment and office centers in people's lives. The performance of a mobile phone has surpassed the processing power of early computers. Internal memory, 16-128GFLASH solid disk, 4G / WiFi broadband Internet access, powerful operating system and rich applications, all these make the functions of office, watching movies, playing games, chatting and other functions that can only be realized on computers before now available on mobile phones The Internet has also become extremely common. The era of the mobile Internet has arrived, and the new framework of smart terminals and cloud services has gradually changed people's traditional li...

AI Technical Summary

Problems solved by technology

[0003] The mobile phone has more and more application functions, the screen is getting bigger and more colorful, the speed of CPU and memory is getting faster and faster, and the uninterrupted opening of data networks such as WiFi is also commonplace, as well as GPS navigation, various The use of sensors is also essential, which makes the power consumption of the system more and more. Although the capacity of the battery is also doubled, people still feel that they are stretched and have to look around with cumbersome chargers every day. A place for charging, or with a bulky power bank, always worried about insufficient power

[0004] The problem with active charging is that you need to find the source of charging, or a socket, or a mobile power supply. The socket is not available everywhere. No matter how large the capacity of the mobile power supply is, it will be exhausted and forget to charge. This is its fatal shortcoming, usually When the power is most needed, the mobile phone and mobile power supply are out of power
